Alexander Motin 2823b6467a Postpone ZVOL media/block size caching till first open. ...

At least on FreeBSD there are no legal way to access media or get its
size without opening device/provider first.  Postponing this caching
allows to skip several disk seeks per ZVOL/snapshot during import.

For HDD pool with 1 ZVOL in dev mode with 1000 snapshots this reduces
pool import time from 40 to 10 seconds.
